Abstract (en)
[origin: WO2015059136A1] The invention relates to a lamp, comprising a first light source (1) for producing a first light having a first spectral distribution, wherein the first light is represented by a first set of chromaticity coordinates in a chromaticity diagram, and comprising a second light source (2) for producing a second light having a second spectral distribution, wherein the second light is represented by a second set of chromaticity coordinates in the chromaticity diagram, the second spectral distribution being different from the first spectral distribution. Furthermore, the lamp has a control unit (3) for controlling the first light source (1) and the second light source (2), which control unit is designed in such a way that an intensity of the first light can be changed independently of an intensity of the second light. The lamp is designed in such a way that the first set of chromaticity coordinates substantially corresponds with the second set of chromaticity coordinates. In this way and by changing the intensities of the first light and of the second light, the weighting of the two lights can be changed in such a way that the melanopic effect factor of the light emitted by the lamp is thereby changed without the color temperature of the light changing.
